AudioQuest Diamond USB-A to Lightning High-Definition Audio Cable
Frequently Bought Together
Product Overview & Specifications
The AudioQuest Diamond Lightning to USB-A is a flagship digital interconnect designed for reference-grade audio playback, charging, and data transfer from Apple Lightning-equipped devices (iPhone, iPad, iPod) to DACs, USB receivers, or digital transports. By eliminating timing jitter, phase delay, and strand-interaction noise, the Diamond Lightning cable turns portable Apple devices into high-performance digital audio sources.
Built with 100% Solid Perfect-Surface Silver (PSS) conductors, the cable provides an exceptionally smooth surface to optimize high-frequency data transfer via skin effect. Signal integrity is maintained using AudioQuest's patented 72V Dielectric-Bias System (DBS) with an integrated RF Trap to polarize insulation molecules, while nitrogen-injected Hard-Cell Foam (HCF) insulation preserves precise signal-pair geometry. A Carbon-Based 3-Layer Noise-Dissipation System (NDS) shields the ground plane from ambient radio-frequency interference (RFI).
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Solid Perfect-Surface Silver (PSS) Conductors: Pure solid-silver conductors eliminate electrical and magnetic strand-interaction distortion while maximizing linear RF noise dissipation.
- 72V Dielectric-Bias System (DBS) with RF Trap: Creates a continuous electrostatic field across the insulation to minimize non-linear time delays (phase shifts) and filter RF noise.
- Carbon-Based 3-Layer Noise-Dissipation System (NDS): Alternating layers of carbon-loaded synthetics and metal absorb and reflect RF energy before it can distort the component's reference ground plane.
- Hard-Cell Foam (HCF) Insulation: Rigid, nitrogen-injected foam creates air pockets that do not absorb or release energy, keeping impedance stable along the cable's entire length.
- Direction-Controlled Conductors: Grain-oriented conductors are listening-tested to ensure induced RF noise is drained away from sensitive receiving audio circuits.
- Apple-Compatible High-Speed Sync & Charge: Connects Lightning-equipped iPad, iPhone, or iPod models to standard USB-A ports for high-resolution audio streaming, charging, and data transfer.
